摘要： In accordance with embodiments of the present disclosure, a debris separator device for use with a casing system may include an impeller having a plurality of blades to generate a vortex of mud in the section of the casing system when the casing system is lowered into a wellbore. The device may also include a baffle disposed in the section of the casing system, the baffle having an annular cup shape that forms an outer circumferential pocket to capture debris from the vortex of mud. The impeller and baffle may enable the debris separator device to separate debris and other debris from a flow of mud through the casing system so that the debris does not clog a float collar of the system. The disclosed debris separator device may be flushable so that the device does not become clogged with debris and can thereby maintain auto-fill through the casing system.
摘要翻译：根据本公开的实施例，与套管系统一起使用的碎片分离器装置可以包括具有多个叶片的叶轮，以在套管系统下降到井眼中时在套管系统的部分中产生泥浆涡旋。该装置还可以包括设置在壳体系统的区段中的挡板，挡板具有环形杯形状，该环形杯形状形成外周袋以从泥浆涡中捕获碎屑。叶轮和挡板可以使碎片分离装置能够将碎屑和其他碎屑与通过套管系统的泥浆流分离，使得碎屑不会堵塞系统的浮环。所公开的碎片分离器装置可以是可冲洗的，使得装置不会被碎屑堵塞并且因此可以维持通过套管系统的自动填充。

摘要： Improved cementing plugs and methods of using these cementing plugs in subterranean wells are disclosed. A cementing plug comprises a hollow mandrel and one or more wiper elements coupled to the mandrel. A nose is coupled to the hollow mandrel and is movable between a retracted position and an extended position. A portion of the nose is positioned within the mandrel when in the retracted position. This portion of the nose is positioned outside the mandrel when in the extended position.
摘要翻译：公开了改进的胶结塞和在地下井中使用这些胶结塞的方法。固井塞包括中空心轴和联接至心轴的一个或多个擦拭器元件。鼻部联接到中空心轴并且可在缩回位置和延伸位置之间移动。当处于缩回位置时，鼻部的一部分定位在心轴内。当处于延伸位置时，这部分鼻子位于心轴外部。
